Taylor Swift has shown time and time again that she really knows how to treat her fans! Throwing a get-together for her Swifties in her own NYC apartment is another in a long line of gracious acts that prove this pop star is a huge sweetheart.

After her worldwide Yahoo live stream yesterday, during which she premiered her infectious new single 'Shake It Off' and her upcoming album '1989,' the 24-year-old invited the fans that were hand-picked to be a part of the audience to make their way to her apartment for a pizza party.

Are they the luckiest Swifties ever?

T. Swift's fans joined her at her home, where they got to chat with the singer, check out her awards and play with her cats Meredith and Olivia Benson. That's it! We're officially green with envy.

Check out some of the tweets below from thrilled fans who got to be a part of such an exciting day -- and a super fun party, by the sounds of it!
